2021 Ford F-150 lighting problems

The Pro Trailer Assist program won't load or work along with constant electrical lamp fault messages when trailering my boat. This is a safety concern because you can't tell if the trailer lights are really working or not while driving. I also experience the turn signals blinking really fast like a bulb is out - when none are actually out. The local dealer's electrical technician has reproduced and confirmed my issues.

The contact owns a 2021 Ford F-150. The contact stated that on several occasions while driving at various speeds, the passenger’s side headlight was not working as intended. The vehicle was taken to the dealer where it was diagnosed that the passenger’s side headlamp needed to be replaced due a failure of the LED screen. The vehicle was repaired; however, the failure reoccurred approximately one year later.
